Abstract
The invention relates to encapsulating tiled timed media data in a server and providing a timed media data bit-stream from encapsulated tiled timed media in a client device. The tiled timed media data comprises timed samples and each timed sample comprises a plurality of spatial subsamples. After having selected at least one spatial subsample from amongst the plurality of spatial subsamples of one of the timed samples, one tile track comprising the selected spatial subsample and one corresponding spatial subsample of each of the other timed samples is created for each selected spatial subsample. One composite track comprising at least one extractor identifying at least one of the created tile tracks is created. Each created track is independently encapsulated in at least one media segment file.
